Question
can a turtle stay under the basking lamp until it drys out??

Answer
I am not sure what you mean. Yes, it is possible for a turtle to dry out and die under a heat lamp- but it would mean something is really wrong.

Normally, they bask until they are warm, then return to the water.

Good luck!
